20 3.10 External Tower Batteries Installation One or more battery cabinets may be connected to the Liebert GXT T230. A cable to connect the battery cabinet and the Liebert GXT T230 is supplied with each battery cabinet. Plug this cable into the battery cabinet and UPS battery sockets slotted fittings on each and ensure that the connection is properly made. Since your UPS has integrated batteries, a compensating current may occur during connection. Figure 11 Liebert GXT T230 with External Battery Cabinet 3.11 Connecting an External Battery Extension NOTE External battery extensions can be replaced during normal operation of the UPS (hot swappable). However, the batteries must NOT be changed when the UPS is in the status Battery Mode operation. The unit checks the battery voltage (a beep is heard) once more and stays in bypass till a constant battery voltage is present.! CAUTION Battery maintenance must be carried out by authorized personnel observing the necessary precautions. 14

21 Installation 3.12 Battery Precautions The batteries installed in the UPS and within the battery extensions may contain electrolyte. Under normal conditions, the containers are dry. A damaged battery may leak electrolyte, which can cause skin and eye irritation. Should this happen, wash the affected area with plenty of water and seek immediate medical attention. Do not open or damage batteries. The released electrolyte is toxic. Voltage is always present on the battery contacts. Even when discharged, a battery has the capacity a high short circuit current which, in addition to causing damage to the battery itself and associated cables, may expose the operator to the risk of burns. The following precautions should be observed when working with batteries: Remove watches, rings and other metal objects. Use tools with insulated handles. The voltage of a single cell of a battery is not dangerous. However a number of cells or battery blocks, connected in series, can produce hazardous voltages. The battery cabinet must not be kept in storage or not used for periods exceeding six months (at 20 C [68 F]) without being recharged (having been charged to 100% at the beginning of any such period). If this period is exceeded, it is essential that the batteries be recharged (which does not require the UPS to be switched on; the UPS just needs to be connected to the mains). If these conditions are not met, the battery performance can no longer be guaranteed. We recommend recharging the batteries at least once every four months. Since new batteries often do not provide full capacity after the initial charge, it may be necessary to carry out a number of discharge/recharge cycles before optimum performance is reached. When replacing batteries, replace with the same type and number of batteries and battery packs. In order to protect the environment, batteries must be disposed of in accordance with local laws concerning the safe disposal of toxic and harmful waste. Do no not dispose of batteries in a fire. The batteries may explode Configuration Program The final step of installation may require custom configuration of your UPS using the enclosed configuration program. Some configuration settings may be changed only while the UPS is Off. These should be set before the UPS is put into full-time use. For most users operating with 230VAC, the factory default settings will be adequate Liebert GXT T230 Configuration Program Features Select one of the three L-N output voltages to match local voltage. Enable/disable auto-restart. Select frequency converter operation with a fixed output frequency of 50 or 60 Hz. Set the Low battery warning alarm time from 2 to 30 minutes. Enable/disable auto-battery test. Set auto-battery test frequency to 7, 14, 21 or 28 days. Specify the number of external battery cabinets connected to the UPS to adjust the remaining run time calculations reported by the system software What You Will Need In addition to the Liebert GXT T230, you will need the configuration program CD and USB cable included in the UPS accessory pack. You must be running Microsoft Windows XP or later on your computer. 15

29 Operation 4.7 Return from Maintenance Bypass Procedure 1. Ensure all switches and circuit breakers upstream of the UPS are closed. 2. Switch both input switches to the On position. 3. Wait at least 30 seconds until the output voltage has stabilized (the yellow LED is lit). 4. Switch the Maintenance switch from BYPASS to UPS and replace the cover. The load is now supplied via internal bypass. 5. Press the Menu button, select Control and press OK. 6. Select UPS ON/OFF and press OK. The LCD displays UPS to ON. 7. Press OK to switch On the inverter. 4.8 Functional Test NOTE Supply to the load is not guaranteed during this test. The test should not be carried out if a critical load is connected to the UPS. The Liebert GXT T230 s controls permit testing the UPS to ensure that the load will be supplied in the event of a mains failure. Before beginning, ensure that the batteries are fully charged. Simulate a mains failure by interrupting the mains supply to the UPS. You can do this by switching Off the input power circuit breaker on the rear panel of the UPS. If the mains supply to the Liebert GXT T230 is protected by an external circuit breaker, opening that circuit breaker will interrupt the mains supply and simulate a power failure. The Liebert GXT T230 is operating properly and the batteries are charged if: An audible signal is heard at four-second intervals The UPS On LED indicator turns Off When the interval between the audible signals decreases to 10 seconds, the UPS has battery reserve energy to supply the load for a maximum of two more minutes. After two minutes, the Liebert GXT T230 will automatically shut down. If the batteries do not supply the load during the simulation, refer to Troubleshooting. To end the simulated mains failure, restore the input power supply to the UPS. The UPS is now ready for operation. NOTE The batteries must be recharged before the complete emergency supply period is again available. 4.9 Remote Emergency Power Off The UPS is equipped with an Emergency Power Off circuit. A factory-installed jumper allows the UPS to operate without an external shutoff switch. If a Remote Emergency Power Off switch is required, a switch with normally closed contacts must be used. Connect the switch contacts to the UPS by removing the factory-installed jumper as shown in Figure

31 Maintenance 5.0 MAINTENANCE 5.1 Testing, Replacing and Disposing of Batteries The Liebert GXT3 is designed to allow the user to replace the internal battery pack safely. Users should use the internal battery pack part numbers in Table 9 for Liebert GXT3 UPS and External Battery Cabinets. Refer to for internal battery pack part numbers for Liebert GXT3 UPS and Liebert External Battery Cabinets: Table 9 Replacement battery pack Unit Model Number Replacement Internal Battery Pack Model Number Quantity Required Liebert UPS: GXT T230 GXT3-240RTBKIT 2 Liebert External Battery Cabinet: GXT3-240TBATTCE GXT3-240RTBKIT 2 Read all safety cautions before proceeding. Contact your local dealer or Emerson representative to obtain the part number and pricing of the appropriate replacement battery pack. Disposal of the UPS and batteries should be carried out by a certified disposal company. Observe all local regulations and laws. Exhausted accumulator batteries are classified as harmful toxic waste and, as such, the law demands that they be disposed of by an authorized recycling centre. The typical battery life cycle is three to five years, at an ambient temperature of 77 F (25 C), but is also dependent on the frequency and duration of mains failures. The battery test (see Battery Test) should be run periodically (every 6 to 12 months) to ascertain the general condition of the batteries and to ensure maximum run time. 25

32 5.2 Easy Battery Replacement Maintenance Open the front panel as shown below. Ensure that a certified service engineer is present to replace the batteries. 1. Open the battery tray DC connectors as shown. 2. Remove the battery trays from the cabinet. 3. Replace the old batteries with a new set. Replacement batteries must be the same type installed at the factory. 4. Reconnect the battery cables. Figure 16 Removing front panel and unlocking battery trays Figure 17 Disconnecting battery tray and battery packs DC connectors 26

33 5.3 Storage Maintenance For extended storage at ambient temperatures cooler that 25 C (77 F), the batteries should be charged for five hours once every four months. At higher storage temperatures. Emerson recommends charging batteries for five hours every two months. After five hours, disconnect from the mains supply or switch Off the input miniature circuit breaker of the UPS. Then remove the UPS connections in the opposite sequence to that described in Installation. Record the battery charging date in the vicinity of the UPS, for example, on its packaging. 5.4 Cleaning 1. Do not clean the UPS with scouring powder or solutions that may dissolve plastic. 2. Do not allow liquid to get inside the UPS. 3. Make sure that the air vents on the UPS are not obstructed. Remove dust from the air vents with a vacuum cleaner. 4. Clean the outside of the UPS by wiping the housing with a dry or slightly damp cloth. 27
